Application filed February 4, 190.9. .Serial No. 476,148.

more particularly to transmission gearing therefor, and has for itsobject to provide'a frictional transmission device, adapted to vary-thespeed of the motion transmitted withoutsliding movement of the frictionmembers relatively.

Another object is to provide a new and eflicient means for communicatingmotion frictionally to a shaft.

Otherobjec'ts and advantages will be-apparentfrom the followingdescription and it' will be understood that changes in the spe-v cificstructure shown and described may be made within the scope of theclaims, and

that any suitable materials maybe used without departing from the spiritof the in-..

Vention.

In the drawin s -forming vaportion of this specification, an in whichlikenumerals of reference indicate similar arts in the several views,Figure l is a to p an vview of the de:

vice and a portion of t e motor sh'aft,Fig.2

' is a cross section through the friction wheel,

.Fig. 3 is a. similar detail of the cam operatinlg means, 4 is a topview of a friction die and amodified forrnof the friction wheel,

Fig. 5 is a similar view of a still further modi-' fication of thedevice. Fig. 6 is a detail hori-' zontal cross sectional view, Fig. 7 isa similar view to Fig. 2 in cross section showing modified meansforengaging the friction'wheel 22 with the shaft 11.

Referring to the drawings, there-is shown a portion of an automobilechassis having a motor shaft 10 thereon, and a laterally ex.

tending counter shaft 11 connected with the otor shaft bymeans oft-hepresent inven= I tion. j Slidably engaged upp'n the inner end of theshaft 10 there is a dis 12 having a collar 13 extending outwardlythereof over the adjacent portlon of the shaft 10,-the eollarhaving aflange 13 at its outer end, against which "impinges a spring 14'en agedaround the: shaft 10 and seated suitab y. The collar 13 "iskeyed to theshaft 10 a ainst rotative 55 movementibut freely for sli g movement 11is disposed inwardly of the disk 12, and has keyed thereon a sleeve 16having outwardly oflset arms 17 at one end thereof, provided withregistering perforations (18 therein. A double cross head member 1 9comthrough having quadri-sp aced peripheral pins is engaged pivotally bymeans of two of the. pins in the perforations 18. A friction maining.pins 20 and comprises an annular disk engaging portion 23 enlargedcentrally and restricted gradually toward its opposite peripheral edgesand disposed in close content with the friction disk.12. The wheel 22 isprovided with an interior flange 24, to WhlCh there is secured acollar-25 having a longitudinal tubular extension 26 enlarged at itsouterend 26to form a bearing for a Jpurpose'to be subsequentlyindicated.

.Socket portions of a suitable'type are carried by the wheel 22,'preferably adjacent to one sidewhere the wheel will bear against theouter portion of the disk 12, the sockets beingerigaged overthe pins 20.of the 111G111, ber 19. Disposed revolubly' upon the shaft -11 adjacentto the bearing 27 there-is an acon provided with a eripheral groove 30on "its outer face and a apted to fit snugly in the bearing 27, asshown. Balls are engaged between the groove 30 and the adjacent faces ofthe bearing 27.

The outer end of the actuating member 28 is provided with an engagingflange 41 adapt connections for-rotating the member 28 to oscillate thewheel 22 .tov vary the point of its contactwith the. disk 12. ,As shown,the

around receiving an endless belt carried by.

the wheel 43 for o eration of the device It will be understood thatifdesired the groove may be provided with a series of peripheral srocket teeth for the engagement thereover' of 'achain to be extended tosuitable points for eng ement with suitable operating rn'eans-'lheiiange 31 may alsobe provided with gear teeth and connected with anoperatin lever at another pointrby means of suitab egears. It will beseen that when the point of contact between the wheel 22 and the disk 12is shifted to the center of the 5 under the action of the spring 14. Theshaft wheel 22 is engaged pivotally over the retuating member 28 havinga flange 29 thereprising a collar having an oval opening thereed forengagement with suitable operative flange 41 is provided with a groovethere'- an adjacent wheel'42 to which is connected 7 disk 12 the speedof the wheel 22 will be relatively slower than that of the disk 12. Ifthe point of contact is shifted outwardly of the center of the disk itwill be understood of course that the speed of the wheel 22 will becorrespondingly Increased, the movement ofthe wheel being induced in onedirection when engaged with the disk on one side of its 'center andbeing rotated in an opposite direction when its point of contact isshifted to the opposite side of the disk.

Suitable connections may be made between the shaft 11 and-a point ofapplication for power.

It will beunderstood that the use of this mechanism will not be limitedto automobiles, but may be adapted to use in various machines forconverting and transmitting motion. Fig. 4 shows a modified form of thewheel 22 the friction portion 22 having a series of smooth faces set atdifierent angles Withrelation to the axis of the wheel.

In Fig. 5 there is shown a still further modification of the wheel 22and of the disk 12, the disk having a series of concentric I groovestherein, andthe wheel 22 having a series of peripheral ribs thereonadapted to meshing engagement in the grooves. T he wheel shown in Fig. 5is gradually reduced in diameter from the center to either end thereof.

What is claimed is 1. The combination with a revoluble disk and arevoluble shaft adjacent thereto of a wheel having a laterally arcuateperipheral 'face multi-pivotally mounted upon said shaft and disposed incontact. with said disk, and

. means for oscillating said wheel to vary the point oiits engagementwith said disk.

2. The combination with a revoluble shaft of a contact disk slidablykeyed thereon, and

, means tending to yieldingly force said con tact disk in 'a constantdirection longitudinally of said shaft, 2. second shaft revolublymounted at right angles with said first named shaft, a multi-pivotedwheel carried by said second named shaft, and disposed in contact withsaid disk, the face of said wheel being reduced laterally towarditsopposite edges, and means for oscillating said wheel alter the point ofcontact between said wheel longitudinally of said second named shaft toand said disk.

3. The combination with a multi-pivoted revoluble memberof an axialextension having a socket formed therein, and a revoluble member mountedeccentrically with relation to the axis of said revoluble member andengaged in said socket, for oscillation of said first named revolublemember upon rotation ofsaid second named revoluble member.

4. The. combination with a universal joint of a roller member carriedthereby having an axial extension, and a revoluble member rotating upona fixed axis adjacent thereto,

.said axial extension being engaged eccentrically with said last namedrevoluble ,mem-

ber,- and means for rotating the last named revoluble member.

5. The combination with a revoluble meniber having a friction surface,of a second revo-- luble member havinga laterally arcuate .peripheralcontact member disposed against said first named revoluble member andbeing pivoted for universal oscillation longitudinally of its axis, andmeans for oscillating the second named revoluble member to alter theoint of its contact with said first named revo uble member. 6. Thecombinat on with a revoluble member havmg a frictlon surface, of asecond revoluble member having a laterally arcuate pe;'

with said actuating member, and means for operating said actuatingmember.

7. A transmission gearing including a revoluble driving member, atransverse revoluble shaft adjacent thereto, a revoluble. driven memberhaving a periphery convex longi tudirially of its axis oscillateablymounted upon sa-i'd shaft, and means for osclllating said driven member.

8. A transmission gearing comprising a revoluble disk and a revolubleshaft having a wheel mounted thereon, the

which is convex in arallel re 'ation to the axis thereof, said w eelbeing pivoted for universal oscillation upon said shaft and disposedincontact with said disk, an axially extending member carried by saidwheel, and a revoluble actuating member mounted upon afixed axisadjacent to said wheel said axially extending member being eccentricallyengaged with said actuating member.

In testimony whereof I affix my signature, in presence of two witnesses.
